Importance of soccer players shifting with the ball (Defensive Movement).

I have found that First Defender/Second Defender is easy to teach, but that the concept of "Third Defender" can be confusing to young players.

Teach your Left side and Right side players (e.g., RFB and LFB) NOT to go past the Center of the field except in an emergency.

The Center Forward is critical to your offense and should score or assist in 1-3 goals per game.

Aggressive Receiving is a better way to teach receiving and will result in a big improvement in your players and their ability to retain the ball.
